JOHN R. JONES, OF PHILADELPHIA, PENNSYLVANIA.

ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 573,000, dated December 15, 1896.

Application filed June 29, 1896.

To all whom it may concern.-

Be it known that 1, JOHN R. JONES, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Rolling-Mills, which improve ment is fully set forth in the following specification.

My invention consists of a novel construction of rolling-mill in which space is economized and the gearing or other power-transmission devices employed are so arranged and assembled with respect to each other that a maximum degree of efliciency is obtained with a minimum expenditure of power, provision being made for rolling and reducing each billet successively without causing the attendants to travel over a large extent of space. 1

It further consists of novel details of construction, all as'will be hereinafter set forth, and specifically pointed out in the claims.

Figure 1 represents a plan view of a rollinginill embodying myinvention, a portion of the housing employed being shown in' section on line at m, Fig. 2. Fig. 2 represents a side elevation of the front of Fig. 1. Fig. 3 represents a side elevation of the middle or intermediate mechanism of the mill seen in Fig. 1. Fig. 4 represents an elevation of the rear of the mill seen in Fig. 1. Fig. 5 represents a section on line 00 Fig. 1. Fig. represents an end elevation of Fig. 1. Fig. 7 represents a section on line so a, Fig. 1, showing the direction of rotation of the rolls and the initial passage of the billet therethrough. Fig. 8 represents a section on line y 3 Fig. 1, showing the direction of rotation of the rolls and the path of the billet on its return; Fig. 9 represents a section on line y y, Fig. 1. Fig. 10 represents a section on line .2 2, Fig. 1, showing the direction of rotation of the rolls and the travel of the billet during its final pass. Figs. 11 to 22, inclusive, represent the successive shapes the billet is caused to assume after each pass through the rolls in the direction indicated in Figs. 7 to 10, inclusive. Fig. 23 represents a plan view of the rollingmill in which the same apparatus is employed with belts used as the actuating means insteadof gearing. Fig. "4 represents a side elevation of Fig. 23. Figs. and 26 reprefierial No. 597,357. (No modelh sent end elevations of Fig. 21. Fig. 27 rep-' Similar. letters of reference indicate corrcspondin g parts in the several figures.

9O designates a coupling by means of which power is transmitted from the gear 88 to the 101191, which has its hearings in the housings 92.

93 and 94 designate grooves or channels which are located in the roll 91 and are in alinement with the grooves 95 and 96 of the adjacent roll 97, which has its bearings in the housings 92.

98 designates a coupling by means of which power is transmitted from the gear 99 to the roll 97.

The numerals 100 to 111, inclusive, designate the different shapes which the billet is caused to assume from the first pass to the finished product, as will be understood from Figs. 11 to 22, inclusive, the finished product being seen in said latter figure.

The operation is as follows: By following out the direction of rotation of the train of gearing indicated in Figs. 1 to 6, inclusive, it will be seen that the several rolls will be caused to rotate in the direction indicated by the arrows in Figs. 7 to 10, inclusive, the billet being first passed between the grooves 60 and 58 of the rolls 62 56, thence on between the grooves 28 and 11 of the rolls 27 and 10, and thence through the grooves 95 and 93 of the rolls 97 and 91. The billet is then transferred in the direction indicated by the arrow at the top of Fig. 1 to the grooves 83 and 80 of the rolls 82 and 78, and is passed thence between the glOOX'GS 16 and 18 of the rolls 14 and 20, and thence through the grooves 43 and 45 of the rolls 41 and 47, after which it is transferred in the direction indicated by the arrow at the bottom of Fig. 1 into the grooves (31 and 59 of the rolls 62 and 50, as indicated at the right of Fig. 9, the billet passing between the grooves 29 and 12 of the rolls 27 and 10 to the grooves 96 and 94 of the rolls 97 and 91, and being thence transferred to the space between the grooves 84 and 81 of the rolls 82 and 78, as seen in .Fig. 4 and at the left of Fig. 10, the billet passing thence in the direction indicated by the arrows between the grooves 17 and 19 of the rolls 1.4 and 20 and the grooves 44 and 46 of rolls 41 and 47, as seen in Fig. 2 and at the right of Fig. 10, after which latter pass it assumes the shape of the finished product 111. (Seen in Fig. 22.)

It will thus be apparent that by assembling the rolls in the manner described the passage or reduction of the billet from the blank to the finished product, as seen in Fig. 22-, is effected in a most expeditious manner, as will be clearly understood from Figs. 1 and 7, it

being of course understood that the speed of rotation of the different rolls is varied accordingto requirements as the cross-sectional area of the billet decreases during and after each pass.

- The construction and manner of assembling the rolling-mill seen in Figs. 23 to 29, inclusive, and the path of the billet through the rolls are substantially identical with that already described with reference to the other figures of the drawings, the only material difference being in the application of and the transmission of power from the main shaft to the various other rolls of the mill.

In the plan view seen in Fig. 23, 112 designates the parts of the mill in assembled position.

113 designates a main shaft, to which power may be initially applied by means of the crank-disk 3 or other suitablemeans, said main shaft revolving in suitable bearings 2 and being provided with a fly-wheel 4, as has already been described.

114 and 115 designate pulleys mounted upon the main shaft 113, said pulley 114 having a belt 116 passing therearound by means of which power is transmitted to the pulley 117, which is mounted onthe shaft 118, which latter runs in suitable bearings.

119 designates a pulley mounted on the shaft 118, around which passes the belt 120, by means of which power is transmitted to the pulley 121, which, it will be evident, takes the place of the gear 85, (seen in Fig. 1,) thereby actuating that portion of 122 of the apparatus which corresponds to the portion of the apparatus seen at the left of Fig. 4. In like manner the portion 126 of the apparatus seen in Fig. 23 corresponds to the apparatus seen at the right of Fig. 4, said apparatus 126 being actuated by means of the pulley 125, around which passes the belt 124, which is actuated by means of the pulley 123, mounted 011 the shaft 118.

127 designates a belt which passes around the pulley 115 and actuates the pulley 128, which is mounted on the shaft 129.

130 designates another pulley mounted on the shaft 129, around which passes the belt 131, which actuates the pulley 132 and also the portion 133 of the mill.

134 designates a pulley around which passes a belt 135, which actuates the pulley 136, by which power is transmitted to the portion 137 of the mill which corresponds to that portion of the mill seen at the right of Fig. 2.

The intermediate portion 138 of the apparatus is actuated directly by means of the main shaft 113 in substantially the same manner as is the intermediate portion of the apparatus seen in the plan view in Fig. 1 and in the side elevation in Fig. 3.

The operation of the parts seen in Figs. 23 to 29, inclusive, need not be described in detail, since their operation is substantially identical with the foregoing figures of the drawings, as stated, the direction of rotation of the sets of rolls being the same as seen in Figs. 7 to 10, inclusive, and itbein g of course understood that the speed of rotation is varied as the cross-sectional area of the billet decreases after each pass.

It will of course be evident that various changes may be made by those skilled in the art which will come within the spirit of my invention, and I do not therefore desire to be restricted in every instance to the exact structure and manner of assembling the above parts which I have herein shown and described.

It will of course be understood that while I have described the parts 6 9 13 21 23, &c., as couplings they are in reality spindles with which the coupling-boxes engage, the latter being constructed in the usual manner and being omitted from the drawings for the sake of clearness of illustration.

The coupling-boxes are substantially equal to the length of the spindle and fit the same easily, said boxes being separated and one half of one of the couplings engaging the journal or neck of the roll and the spindle adjacent thereto, while the other half of said coupling engages the opposite end of the same spindle and the neck or journal of the adjacent roll.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
